Swagelok Company is a $2 billion privately held developer of fluid system products, assemblies, and services for the oil and gas, chemical and petrochemical, [2] semiconductor, and transportation industries.
The control system may involve human input or may be computerised (computer numerical control or CNC). [2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The dangers of accessing difficult to reach lubrication points while a machine is ...
serve as a lubricant as the fittings are forced together (vegetable oil). Various types of pipe dope formulation exist, the appropriate type being determined by the application, e.g., pneumatic, hydraulic, caustic, etc., [4] as well as the expected pressure. Improper selection of the type of pipe dope may result in leakage despite the best ...
Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths ...
Later systems collect oil in a sump, from where it can be collected and pumped around the engine again, usually after rudimentary filtering. This system has long been the norm for larger internal combustion engines. A pumped oil system can use higher oil pressures and so makes the use of hydrostatic bearings easier. These gave a greater load ...
The Roscoe type lubricator improved the situation by providing a valve with which to regulate the flow of steam and hence lubricant. Setting the valve correctly required experience and depended on the speed of the train. [2] The Roscoe lubricator was invented by James Roscoe in 1862 and patented in British Patent 1337. It incorporated two ...
Selecting a nozzle based on the pattern and other spray characteristics that are required generally yields good results. [5] Since spray nozzles are designed to perform under many different spraying conditions, more than one nozzle may meet the requirements for a given application. Surfaces may be sprayed with any pattern shape.
where is the tap drill size, is the major diameter of the tap (e.g., 10 mm for a M10×1.5 tap), and pitch is the pitch of the thread (1.5 mm in the case of a standard M10 tap) and so the correct drill size is 8.5 mm. This works for both fine and coarse pitches, and also produces an approximate 75% thread.
